Is a json file even necessary just to create a node? Does 'chef-client
-t token' only create the registration? If so, why? Seems fairly
intuitive that it'd create an empty node also.

Also, as a shortcut, you can take advantage of a bashism to avoid
needlessly creating a temp file:

chef-client -j <(echo '{"recipes": [ ]}') -t "token"
